Common Bentwing Bats are found in northern and eastern Australia, in northern Western Australia, Northern Territory, Queensland, New South Wales, Victoria and south-eastern South Australia.
The Common Bentwing Bat prefers moist environments where it roosts in very large numbers in caves, old mines, stormwater tunnels and occasionally buildings. Forages in forests and woodlands and grassland.
Feeding and Diet
By night the Common Bentwing Bat hunts moths and other flying insects.
Female Common Bentwing Bats give birth to their young in summer and roost together in warm, humid maternity caves where there may be up to 3,000 young bats per square metre of ceiling. These bats can live as long as 18 years.
Predators, Parasites and Diseases
Predators of Common Bentwing Bats include owls, pythons, cats and sometimes foxes.
The number of Common Bentwing Bats is thought to have declined in southern Australia over the past 30 years as a result of disturbance of their roosting sites.
